1 Additional Answer
A barometer works by measuring the rise and fall of the air and/or the atmospheric pressure. Once you have properly adjusted a barometer for the proper normal atmospheric pressure in your area, you can use it to calculate weather changes at home, as good as any weatherman you see on television.
